I have a typical problem of getting sick in cold wethersEven If I sit in an AC roomI get these pimples in the groin areas and thighsSome times these become too painful to cause a temperature riseMy body is so much unsuitable to coldnesslike a high speed fan on a cool dayAny of these cause pimples either on thighd or in scrotum or rarely on other parts of the bodyCan I get any medical help to overcome this problem.also this problem started after crossing 30years of age.I am not sure if age has anything to do with this problem.Also too cool a whether cause stiffness in muscles(neck,back etc.).
